If you mean VLAN with logical LAN segment, usually subnets do not use several VLANs (I do not even know if it is possible for a subnet to spread over several VLANs).
A Vlan is nothing else than a physical network segment being virtualized, so you don't need multiple switches per separate segment, and also not multiple cables for connecting switches in different physical locations, but belonging to the same physical segment. (The latter is achieved with Vlan-Trunking, in Cisco-Lingua.) So, yes, a logical LAN segment is a Vlan, probably spanned over multiple switches.
Yes, I am aware of that. I was just not sure about the "logical LAN segment" expression.

Maybe you can predict the answer by now: You can perfectly connect multiple different Vlans together with bridging, do make a subnet span several Vlans. After thinking hard, I still can't see any real world use case for such a configuration, though. Depending on the network vendor allowing you to create senseless configurations, you might have a hard time to configure such a tangle.;-)

(A switch is btw. nothing else than a multi-port bridge.)
Thanks for the feedback. Indeed, I do not remember such a situation when I was working with network teams.
